Video footage lagging on Macbook Pro

Dear Phantom Pilotes,
i got a phantom 3 advanced for over 3 months now. It is a great drone and i am very happy about it.
However when i transfer the footage i took from my drone on my Macbook pro and i view them in quicktime or VLC the video is very laggy. (Almost unwatchable)

What i dont understand is when i transfer the same footage to my ipad Mini 2. There is no lag at all.
shouldn't a Macbook Pro be more powerful than a ipad ? So why is it having problems reading it on my Macbook and not on my ipad.
i'm confused.

OP has an Advanced, so it might be 2.7K but not 4K. I tried the MPlayerX on an old i7 17inch MBP which has 'issues' with 4K and it managed 4K much better than VLC or Quicktime (thanks DroneTone). So that might be a route to try.

I'm on a 2013 MBP and can do 4K viewing and editing, but it's a quad processor and retina and twini Intel/Nvidia for video work.. by the same token I have a 2010 Mac Pro 8 core loaded with memory, SSDs, etc and the video card just can't keep up.. :-( So more a video processor issue vs. CPU, but Core 2 Duo is older. May be time for an upgrade if you can and want to process 4K.. Refurb prices on Apple are good (and you can get full Apple Care) .. there's also the used market..
